Sinumerik Alarm 16945 Channel %1 action %2 <ALNX> delayed up to the block end
%1 = Channel ID
%2 = Action number/action name
The currently executing action (e.g. dry run on/off, change skip levels, etc.) should be active immediately, but it can become active not earlier than at the end of the block, since a thread is currently being machined. The action is activated with a slight delay. Example: Dry run is started in the middle of the thread, then traversing at high speed does not start before the next block.
– Alarm display.
Alarm can be switched off via $MN_SUPPRESS_ALARM_MASK bit 17==1.
Clear alarm with the Delete key or NC START.
